Abstract
The utility model relates to a nuclear medicine radiation detection device, include at the one deck phosphor powder of photoresistor surface coating, reuse light-resistant shell parcel photo resistance and phosphor powder. When nuclear radiation irradiates, the fluorescent powder emits visible light under the radiation, the visible light irradiates the photoresistor, the resistance value of the photoresistor can be reduced, the reduced resistance value can be read by adopting a universal meter, and the radiation size is judged. The fluorescent powder adopts fluorescent powder on the inner wall of the fluorescent tube, and the light-shading shell prevents the interference of external visible light. Thereby achieving the purpose of testing radiation.
Description
Technical field
The utility model relates to a kind of radiation detector assembly, particularly a kind of nuclear medicine radiation detector assembly.
Background technology
At present, in the inspection therapeutic process of nuclear medicine, can not carry out the detection normal conditions of radiation.And the specialized equipment of expensive is all adopted in detection.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming, and a kind of nuclear medicine radiation detector assembly of simple in structure, easy to use, reliable and stable, cheap, long-term use is provided.
The technical scheme that the utility model nuclear medicine radiation detector assembly adopts is: in photoresistance surfaces coated layer of fluorescent powder, again with parcel photoresistance of lucifuge shell and fluorescent powder.When nuclear radiation was shone, fluorescent powder received radiation and sends visible light, and visible light shines in the photoresistance again, and the resistance value of photoresistance can descend, and adopted multimeter can read the resistance of decline, judged the size of radiation.Fluorescent powder adopts fluorescent tube inwall fluorescent powder, and the lucifuge shell is the interference that prevents extraneous visible light.Thereby reached the purpose of testing radiation.
The beneficial effect of the utility model is: working stability is simple, with low cost.
Description of drawings
Fig. 1 is the schematic diagram of the utility model.
1. lucifuge shells, 2. fluorescent powder, 3. photoresistance among the figure.
Embodiment
In Fig. 1, in photoresistance 3 surfaces coated layer of fluorescent powder 2, again with the 1 parcel photoresistance 3 and fluorescent powder 2 of lucifuge shell.Fluorescent powder 2 adopts fluorescent tube inwall fluorescent powder.
Claims (2)
1. a nuclear medicine radiation detector assembly comprises lucifuge shell, fluorescent powder, photoresistance, it is characterized in that: in photoresistance surfaces coated layer of fluorescent powder, again with parcel photoresistance of lucifuge shell and fluorescent powder.
2. according to the said nuclear medicine radiation detector assembly of claim 1, it is characterized in that: fluorescent powder adopts fluorescent tube inwall fluorescent powder.
